Default Fill'er Up?

Hello Jean,
Depends on what you're filling. For foam, many builders use lightweight spackle, I've tried "Red Devil" and it seems pretty good. There are many other brands available.
On balsa, I've used microballons and epoxy, it works well but is hard to sand and if you overdo the epoxy, it can be heavy.
I sometimes make my own "mix" of balsa filler from balsa sanding residue (dust) and Titebond wood glue. It can be thinned with water, also.
Just a couple of ideas!
Ron

Thanks to the both of you, And by the way I'm using balsa. I was thinking of wood gloo, but When U say Epoxy, do you meen epoxy glue, or epoxy resin?

Default Which Adhesive?

Hello Jean,
The epoxy I use is a 2 part adhesive, like this;
http://www.zapglue.com/Epoxy.html
http://www.sigmfg.com/IndexText/SIGEG001.html
There are different formulas, usually "5 minute" curing (Devcon in a popular brand) is for field repairs and the 30 minute type is for general building, often used with fiberglass tape or carbon fiber as a reinforcement.
Here's a link to the most common adhesives for hobby use;
